Nasturtiums are classic, easy-to-grow flowers that attract pollinators, are fairly drought tolerant, are deer and rabbit resistant, and begin blooming 8 to 12 weeks after sowing. While usually grown as an annual, nasturtiums are perennial in USDA zones 10 and warmer. The genus, Tropaeolum<\/em>, is Greek for ‘trophy’, in reference to its shield-shaped leaves. <\/p>\n\n\n\n

The word, nasturtium, comes from nasus<\/em> and tortus<\/em>, roughly translating as ‘nose twister’ due to the plant’s spicy scent and peppery taste. Nasturtium flowers, leaves and seeds are edible. Seeds can pickled and used as a substitute for capers or dried and used as a substitute for peppercorns. If you were wondering how to grow nasturtiums from seed, you’ve come to the right place!<\/p>\n\n\n\n

General Sowing<\/h2>\n\n\n\n

When to Sow Outside:<\/strong> RECOMMENDED. 1 to 2 weeks after your average last frost date. Mild Climates: Sow in fall for winter bloom. Ideal soil temperature for germination is 55\u00b0\u201365\u00b0F.<\/p>\n\n\n\n

When to Start Inside:<\/strong> Not recommended. 2 to 4 weeks before your average last frost date. Roots sensitive to transplant disturbance; sow in biodegradable pots that can be directly planted in the ground.<\/p>\n\n\n\n

Indoor Sowing<\/h2>\n\n\n\n

Soak seed in water for 12 to 24 hours before sowing. Use a lightweight seed starting mix\/medium (sterile, and lighter than potting mix), and sow seeds \u00bd”- 1″ deep. Sow 3 seeds per pot, thinning to the strongest plant once leaves appear (clip extra plants at the soil level using scissors). The strongest plant may not be the tallest; look for thick, strong stems and deep color. By thinning early, you minimize the negative impact of crowding, like stretching for light.

Containers<\/h3>\n\n\n\n

Containers should be clean, sanitized, and have drainage holes. If you choose to sow in cell packs, you may need to up-pot seedlings once into larger containers before transplanting outside<\/p>\n\n\n\n

Transplanting<\/h3>\n\n\n\n

After hardening off, transplant seedlings 8″-12″ apart.<\/p>\n\n\n\n

Outdoor Sowing<\/h2>\n\n\n\n

Sowing preparation and spacing<\/h3>\n\n\n\n

Choose an area in full to part sun. Nasturtiums grow well in poor to average well-drained soil. If drainage needs to be improved, add organic material or grow on mounds.<\/p>\n\n\n\n

Thinning<\/h3>\n\n\n\n

When plants are 2″ tall thin to 1 plant every 8″-12″.<\/p>\n\n\n\n

Water<\/h3>\n\n\n\n

Though nasturtium is fairly drought tolerant once established, it does best with regular waterings.<\/p>\n\n\n\n

Fertilization<\/h3>\n\n\n\n

Fertilizer usually is not necessary; too much nitrogen produces excess foliage and fewer flowers; add a phosphorous-rich, liquid fertilizer to encourage flowers if needed.<\/p>\n\n\n\n

Weeding<\/h3>\n\n\n\n

Keep plants well weeded. Weeds compete with crops for light, nutrients, and water, and can harbor insects and diseases.<\/p>\n\n\n\n

Special care<\/h3>\n\n\n\n

Deadhead (remove spent blossoms) for optimum number of blooms and to prevent seed formation. Nasturtium may self-sow.<\/p>\n\n\n\n

Harvesting<\/h2>\n\n\n\n

Harvest leaves and flowers in the morning, if possible, when they are more hydrated and cooler, rather than later in the day.<\/p>\n\n\n\n

Common Pests and Disease<\/h2>\n\n\n\n

Nasturtiums can attract aphids which makes them an excellent trap crop, pulling the pest away from your other plants. Simply spray aphids off with a strong stream of water.<\/p>\n","protected":false},"excerpt":{"rendered":"
